Referring now in detail to the drawings, I0 and ladesignatea pair of parallel rails mounted on parallel transverse ties 'l I. Inaccordance with the invention, there is `provided apparatus forlubricating the inner surface of the head of the rail Illa. Theapparatus comprises generally of a tank I3 embedded within the roadbedadjacent the rail I 0 and connected by conduit I4 to a discharge deviceI5 mounted on a clamp I6 fixed to said rail Illa.. The apparatusfurthermore comprises operating mechanism I9 actuated by the wave ofrail I0 when a train passes over the rails for forcing lubricant withinthe tank through the conduit I4 to said discharge device I5, whereby todeposit lubricant on the head-of said rail I 0a, as will be explained indetail hereinafter.

' The tank |3`comprises a bottom plate 20 formed with a circular raisedportion 2| and an outwardly extending peripheral flange 22. The plateA20is formed with a central screw-threaded opening 23;' and also Withfapassage 24 connecting an upper surface of the raised portion 2| with an,

outer edge of the flange 22@ Mounted on the platelll, is a cylindricalmember 25, the lower end whereof snugly receives the raised portion 2|of the plate and contacts flange 22.

Mounted on top of the cylindrical member 25, is a tank head or member26, preferably in the form of a casting and having an annular horizontalflange or wall portion 21 aligned with the flange 22 and formed with acircular groove 28 on the undersurface thereof receiving the upper edgeof the cylinder 25. The flanges 22 and 21 are formed with aligned pairsof openings receiving connecting bolts 29 which serve to clamp the head26 and the plate 26 against opposite sides of the cylinder 25. Extendingfrom the horizontal flange or portion 21 of said member 26, areupstanding parallel side walls 30, disposed parallel to andpreferablybetween the ties an upstanding end wall 3| parallel to therails, and an upwardly and "outwardly inclined end wall 32 opposite tothe wall 3i. The -walls 30, 3| and 32 are all interconnected by a topwall 33 parallel to the flange Aor portion 21.

The end wall 3| is formed withV a screwthreaded opening 35, to whichthere is scr-ewed one end of the conduit I4. The top wall 33 is formedwith a central boss 36, having a through opening 31 aligned with thethreaded opening 23 in the bottom plate 20. The top vwall 33 isfurthermore formed with an opening B0 for a screw plug 4|. When theplugr is removed, a stick may be inserted to determine the amount oflubricant in the tank. Said top wall 33 is furthermore formed with adownwardly extending boss 42, having a through opening 42a., for thepurpose hereinafter appearing. Adjacent the inclined wall 32, the topwall 33 is formed with an oblong opening 43 to receive a clampingclosure 44 which may be opened for the purpose of inserting lubricantinto the tank. The head 26 has a horizontal bracket extension 46 atsubstantially the level of top wall 33, projecting from wall 3| beneaththe adjacent rail i6.

Screwed within opening 23 of bottom plate 20, is a screw 50 projectingsomewhat above the plate and being formed with a depression or socket atits upper surface. Journalled within the through opening31 of the boss36, is an axial member 5| provided with a collar 52 contacting theunderedge of the boss. The portion 53 of the member 5| above thecollar52 is smooth, whereas the portion 54 below said collar isscrewthreaded. The lower end of the member 5| is formed with a socket;and a metal balll55 is interposed between the lower endof the member 5|and the upper end of the member 56, said ball being received within theopposed sockets of said members. A packing gland may be screwed withinthe boss 52.

Disposed within the tank is a piston 56 comprising a plate 51 formedwith a central threaded opening engaging the lthreaded portion 54 of themember 5|. Bolted to the underside of the member 51 is a plate 58clamping thereto an annular wiper 6D engaging lthe inner surface of thecylindrical wall 25. -A vertical guide rod 6| parallel to the axialmember v5| -may extend through the tank, `passing through registerirgVopening in the plates 51, ESYandfbeing fixed at the ends thereof to the-head 26 andplate 26. It will now be understood that as the member 5|`is rotated (in the manner'to be explained hereinafter) the piston 56will move upv or down depending upon the direction of rotation, ltheguide rod 6| preventing the piston from rotating.

The operating mechanism |9 for forcing grease within the 'tank and-abovethe'piston through the conduit |4, comprises a bearing 64 mounted on thebracket extension 46 and rotatably supporting a horizontal shaft 65disposed at right angles to the rail IU. Attached to one end of theshaft 65, as by a universal joint 66, is a shaft 61. Pivoted about avertical axis to the top wall 33 of the tank, as at 68 directly belowthe universal joint 66, is a bracket 69 provided with a pair of spacedbearings 10, in which the shaft 61 is rotatably supported. On said shaft61 and between the bearings 1U, is a worm 1| meshing with a worm wheel12 xed on the upper end of the lt'member 5|.

worm 1| in mesh with the Worm wheel 12. To

thisend, there is slidably mounted within the opening 42a`of boss 42, apin 14 having a collar 15 at the lower end thereof. Interposed betweenthe collar 15 and the boss 42, is a coil compression spring 11. At theupper end thereof,` pin 14 is provided with a head 18 and a handle 19.The head 18 is normally in engagement with the outer end of the bracket69 for retaining the worm 1| in engagement with the worm wheel 12. Whenthe piston 56 moves tolward the top, the same will engage the lower endof the pin 14 to lift the latter against the pressure of the spring 11to raise the head 18 above the lower end of the bracket 69, thuspermitting said bracket to swing about the pivot 68 to the dotted lineposition shown in Fig. 1, the worm 1| thus becoming disengaged from theworm wheel 12. To swing the bracket to the dotted line position in Fig.l upon release thereof, there is provided on the top wall 33 a stop 8D,a compression spring 8| being interposed between said stop and thebracket and pressing against said bracket.

On the shaft 65 is a clutch 85 adapted to be rotated by the wave motionof the rail lO, to intermittently rotate the shaft 65 when trains passover the rail. The clutch comprises a sleeve 86 xed on the end of theshaft 65. The sleeve 86 is formed with a plurality of curved teeth 81.Rotatably mounted on said shaft 65 and between the sleeve `86 and thebearing 64, is a member 88 having an annular ange 89 surrounding theteeth 81. An annular liner 96 of hardened metal may be xed to the innersurface of the flange 89. Between the liner 9|) and the teeth, arerollers 9| disposed in the notches or spaces formed between the teethand said liner. Springs 92 within sockets formed at the ends of theteeth 81 serve to press the rollers away from the ends of the teethtoward the shallow portions of the notches. A cover 94 frictionallyfitted on the ange 89 has an end wall 95 covering the notches andretaining the rollers therein.

Integrally formed with the member 88, is an arm 91 on the upper end ofwhich is a roller 98 engaging the undersurface of the adjacent rail l0.A spring |00 fixed to the member 88 at one end and to the bracket 46 atthe opposite end, serves to maintain the roller 98 in constantengagement with the rail.

It will now be understood that when the rail is depressed the member 88will be rotated about the shaft 65, causing the rollers 9| to grip theteeth 81 and rotate the shaft 65. rail moves up, the spring |00 willrotate the member 88 in an opposite direction without causing rotationof the sleeve 86 or shaft 65. The shaft 65 will thus be intermittentlyrotated when a train passes over the rail. Rotation of the When the sas'shaft 65 will cause intermittent rrotation 'of the Tscr'ew 5| in adirection for moving the piston 'upwardly to press the lubricant in thetank and above said piston, through the conduit I4 to the dischargemember I5. 1

There is further mounted on the bracket 46, a friction brake 46a, havingsemi-cylindrical portions vengaging the sleeve 86 and preventingretrograde movement of said sleeve.v y

`A vent pipe 24a may be attached tothe base l plate 20 for communicationwith the interior of the tank through the passage 24, said pipeextending above the tank as shown` in' Fig. 2 4of the drawings. The tankmay be supported on horizontal boards 20a and by vertical board 20h',engaging at its lower end one of the boards 20ctl and at its upper endthe bracket extension '46; y It will be notedv that the distancebetweenthe walls 30 of the tank head 26 is less than the diameter rof the tank.Thus, should it be required to embed the tank between railA ties whichare relatively close together, the tank body may be disposed beneath theties and the tank head disposed between the ties. Thus, if the 'diameterof the tank body is greater than the distance between a pair of ties,the body may be located below the level of the ties with the headprojecting between the ties.

A, The lubricant discharge device I5 is mounted on the clamp I6, asshown in Fig. 2 of the drawings. Said clamp comprises a pair ofsymmetrically disposed members |05 and |06, engaging lopposite edges ofthe base of the rail. The

member |06 comprises an elongated folded-over channel-shaped portion|01, receiving one edge of the rail base and provided with a centraldepending apertured ear I 08. The member |05 likewise comprises anelongated channel-shaped portion |09 receiving the other edge of therail base. and provided with a depending apertured ear aligned with theear |08. A bolt IIIl passing through the ears |08, III) serves to fixthe members |05, |06 to the rail. Portion |09 of clamp member |05 isIprovided with a pair of spaced, horizontal, threaded openings I|2receiving therethrough, screws II3, the inner ends whereof are adaptedto engage thev outer end edge of the base of therail, as shown in Fig. 6of the drawings. Said portion |09 is also formed with a pair of spacedvertical screw-threaded openings, into which are screwed vertical screwsII'4, each provided with a pair of spaced locknuts II5. Mounted on thescrews II4 and supportedby the nuts I I5, is the discharge device I5.

Said device comprises a member H preferably in the form of a castinghaving horizontal end extensions II'I provided with slots Illa.perpendicular to the rail, receiving therethrough the screws |I4. Thelock-nuts |I5"are disposed on opposite sides of extensions II'I. Theheight ofthe discharge member may be regulated by suitably manipulatingsaid lock-nuts II5.y The member ||6 has a flat upper surface |I9,and isformed with a pair of parallel elongated chambers |20, |2| both open atthe top. Said chambers may be interconnected by spaced transverseopenings |22. The member |I6 is furthermore formed with a central nipple|23 cornmunicating with the middle of the chamber |20. The nipple |23 iscurved downwardly and is attached to one end of the conduit I 4. Saidmember I I6 is furthermore formed with a plurality of vertical throughopenings |25 for the purpose hereinafter appearing. y

On top of the member II6 and contacting the surface ||9 thereof, is awasher or gasket I 26, having a slot I 2'I registering with the chamber|2I. On the gasket |26 are a pair of thin angular symmetrically disposedplates |29 and |30, preferably made of thin sheet metal, such as sheetsteel. yEach has a horizontal wall and a vertical wall. The vertical-walls'are close together forming therebetween a thin narrow slot |3|adisposed directly above and registering with the chamber I2I. areinterposed between the vertical portions of the members |29, |30,adjacent the ends thereof and forming end walls for the slot |3Ia. Saidplates are weldedor riveted to said vertical walls. On the horizontalportions o-f the members |29, |30, is a plate I3| formed with a slotthrough which the vertical portions of said members pass. The plate I3!is bolted to the member H0 by bolts |32 passing through the boltopenings |25.

lt will now be understood that lubricant pass'- ing through the conduitI4 will enter the chamber |20, pass through the openings |22 to thechamber I2! and will then be forced upwardly through the slot I 3 Iaonto the side surface of the head of the rail. The discharge member I5may be so adjusted in height as to bring the upper edge of the members|29, |30 substantially at the lower edge of the head of the rail. Thedischarge device I5 furthermore may be adjusted toward the rail byloosening lock-nuts II 5. The lubricant, preferably a heavy graphitegrease, passing through the slot I3|a will be discharged in a thin sheetwhich will coil as it is deposited on the head of the rail; As the trainpasses over the rails, causingwaving of the rail, the lubricant isdischarged onto the side wall of the rail head and is taken up by theflanges of the wheels passing over the rail.

The discharge end of member I5 is so thin that the flanges of wheelspassing over the rail will not strike or pound or contact the same, thusinsuring long life without material wear. The flanges of the wheels pickup the discharged lubricant without contacting the discharge device.

In Figs. 10, l1, 12, 13 and 14 ythere is disclosed another form ofoperating mechanism for forcing lubricant from a tank or reservoirthrough a conduit to the discharge device I5. As shown in said figures,there is provided a tank Ia substantially similar to the tank I3 shownin Fig. 2. Mounted on the upper end of the axial screw 5|a of said tankis a one-way clutch 85a similar to the clutch 85 shown in Fig. 3 of thedrawings. The clutch 85a comprises a member 82a similar tothe member 83of Fig. 3, but having a horizontal pin extension |40, for the purposehere inafter appearing. yThere is slidably mounted on the' tank head26a, a release pin 14a pressed downwardly by a compression spring, andformed at its upper end with 'a slot |4I. A transverse pin |42 removablymounted at the upper end of member 14a crosses said slot. On said pinand within said slot, is a roller I 42a. Adjacent the bottom of the slot|4| is another pin |43 carrying a roller For the purpose hereinafterappearing, the tank head 26a is provided with a pair of apertured ears I45 supporting a transverse pin I 46. Pivo-ted on said pin, is a bellcrank lever |41, having one arm |48 substantially in horizontal positionand projecting beneath the adjacent rail I0. Said arm |48 is formed-witha slot |40 receiving therethrough a screw |50 fixed to said arm by apair of lock-nuts |5I. At the upper end of the screw vis`rotatablymounted a roller |52 engaging the A pair of thin metal plates |3|bunderside of the rail. 'Ihe lever |41 furthermore comprises anupstanding arm |55 formed with a slot |56 at its upper end. Within saidslot is a block |51 which may be fixed to the arm |55 in variousadjusted positions along said arm, by a set screw |58. The blockA |51 isprovided with a transverse pin |60 having projecting ends. At one end ofa connecting member |6| is a bifurcated portion |62 receiving the upperend of the arm |51 and formed with apertures engaging the outer ends ofsaid pin |68. The connecting member |6| is formed on the underedgethereof with a notch |65 engaging the pin |4|l on the clutch 85a. Saidmember |6| furthermore passes through the slot |4| and between rollers|42a, |44. A coil tension spring |66 interconnects the arm |55 of thebell crank |41 with the tank head 26a.

It will now be understood that as the rail |G moves up and down duringpassage of a train thereover, the bell crank |41 will be oscillated, inone direction by the rail and in the other direction by the spring |66.The spring |66 maintains roller |52 in contact with the underside ofrail Illa. During oscillation of the bell crank, the connecting member|6| will be reciprocated to oscillate the member 88a of the clutch 85a.Such oscillation of the member 88a will intermittently rotate the screwBla. in one direction to raise the piston for forcing the lubricantthrough the conduit to the discharge device. When the piston strikes theunderside of the pin 14a, said pin will be lifted for raising theconnecting member |6| to disengage the pin |40 from the slot |65.

A friction brake |10 may be mounted on the tank head and provided withsemi-circular portions engaging opposite sides of the toothed portion86a of the clutch. The screw 5|al may be formed with a polygonal head|1| at its upper end to receive a wrench, whereby the screw may berotated in a direction to lower the piston after the clutch has beendisengaged, so that the tank may be relled with grease. To permit suchoperation, the pin |42 is rst removed and member |6| swung upwardly outof engagement with pin |40.

It will be noted that the stroke of the connecting rod |6| may be variedby adjusting the position of the screw |50 within the slot |49, and alsoby adjusting the position of the block |51 within the slot |56.

In Fig. l5, the discharge device I is shown in an adjusted position withthe slot |3|a substantially flush with the side of the rail and thevertical portion of the plate |30 substantially contacting said head anddisposed therebeneath.

With such arrangement, the discharge device may be placed at the curveof the rail where the anges of the wheels press against the rail headdue to centrifugal force, the lubricant being discharged into they spacebetween the wheel flanges and the rail head, whereby the flanges wipethe lubricant against the rail head, the latter acting as a wiperwithout the discharge device being contacted by the flanges. A highlyefficient lubrication of the rails and wheel flanges thus result.

If desired, the tanks and operating mechanisms of Figs. 2 and 1l may beinstalled in reverse positions at 180 from the positions shown in saidfigures, in which event the tanks will bey located between the railsinstead of outside of the rails.

It will now also be understood that the operating mechanisms illustratedin the drawings are not attached or anchored to the rail, the rollersmerely contacting the underside of the rail. Such constructionsimplifies installation and permits creeping of the rail withoutaffecting the operating mechanism.

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as Various changes might be made in the embodiment above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawings is to be interpreted as illustrative and not in alimiting sense.
